I have a text box which I would like to include a £ sign whenever the user begins to type in a number.
For example: £32
How would I do this:
#Html.TextBox("amountFrom", "", new { #class = "form-control", #placeholder = "£" })
At the moment I just have a placeholder which puts a '£' sign in until the user types in an number. I would like the sign to appear immediately after the user starts typing.
A quick and dirty fix would be to use JavaScript or jQuery. When the text box changes, a £ is added to the front of whatever is already in the text box.
#Html.TextBox("amountFrom", "", new { #class = "form-control", #id="price" })
<script>
$(function() {
$('#price').on('input',function() {
var price = $('#price').val();
if (price.substring(0, 1) == '£')
{
price = price.substring(2);
}
$('#price').val('£ ' + price);
});
});
</script>
See this fiddle here : http://jsfiddle.net/49gdh95z/
A slightly better solution might be to use CSS that shows a background image of a pound sign, like StackOverflow uses to show a magnifying glass image on it's search box.
A fiddle for this example can be found here : http://jsfiddle.net/7pjm9v66/
Note that this second example adds the pound sign immediately after something is typed into the input box (and doesn't display beforehand). If you wanted to have the pound sign always display, then you can of course omit the JavaScript and move the CSS it applies directly to the #price element in the CSS.

Is it possible to style the value in the attribute ngModel of an input tag?
Example:
<input class="input" type="text" [(ngModel)] = "myService.text">
Let's say the value of text is '28 packages', can I put 28 in bold?
So if i understand correctly you want to have it bold whenever the value is 28 ?
yes its possible you can use a ng-class with a ternary expression like this
.bold{
font-weight:600;
}
<input type="text" ng-class="myService.text == '28 ? 'bold' : '''" class="input" ng-model="myService.text" />
This is not angular-related rather a CSS related question.
You cannot style only a part of an input in HTML/CSS so you won't be able to do it in angular.
Instead, you can use an input that is hidden behind a div. The idea is that when the user clicks the div, you actually focus the input. When the user types text, you capture the content of the input and fill the div with it, eventually adding <span class"highlight"> around the number of packages.
I prepared you a stackblitz in pure CSS/JS. You can adapt it in angular if you want.
Relevant pieces of code :
HTML :
<span id="hiddenSpan">This is the hidden div. Click it and start typing</span>
<div>
<label for="in">The real input</label>
<input id="in" type="text">
</div>
JS :
const input = document.getElementById('in')
const hiddenSpan = document.getElementById('hiddenSpan')
function onInputChanged() {
let text = input.value
const regex = new RegExp('(\\d+) packages')
let result = regex.exec(text)
if(result) {
hiddenSpan.innerHTML = '<span class="highlight">'+result[1]+'</span> packages'
} else {
hiddenSpan.innerHTML = text
}
}
// Capture keystrokes.
input.addEventListener('keyup', onInputChanged)
// Focus the input when the user clicks the pink div.
hiddenSpan.addEventListener('click', function() {
input.focus()
})
CSS :
#hiddenSpan {
background-color: pink;
}
.highlight {
font-weight: bold;
background-color: greenyellow;
}
Note : the downside is that the blinking caret is not visible anymore. You can take a look at this resource if you want to simulate one.
It is not possible to style certain parts of a text <input> field in bold. However, you can use a contenteditable div instead of a text <input> field. Inside the contenteditable div you can have other HTML tags like <strong> to style certain parts of the text however you like.
I created an Angular directive called contenteditableModel (check out the StackBlitz demo here) and you can use it to perform 2-way binding on a contenteditable element like this:
<div class="input" contenteditable [(contenteditableModel)]="myService.text"></div>
The directive uses regular expressions to automatically check for numbers in the inputted text, and surrounds them in a <strong> tag to make them bold. For example, if you input "28 packages", the innerHTML of the div will be formatted like this (to make "28" bolded):
<strong>28</strong> packages
This is the code used in the directive to perform the formatting:
var inputElement = this.elementRef.nativeElement;
inputElement.innerHTML = inputElement.textContent.replace(/(\d+)/g, "<strong>$1</strong>");
this.change.emit(inputElement.textContent);
You can change the <strong> tag to something else (e.g. <span style="text-decoration: underline"> if you want the text to be underlined instead of bolded).
When performing the formatting, there is an issue where the user's text cursor position will be unexpectedly reset back to the beginning of the contenteditable div. To fix this, I used 2 functions (getOriginalCaretPosition and restoreCaretPosition) to store the user's original cursor position and then restore the position back after the text formatting is performed. These 2 functions are kind of complex and they're not entirely relevant to the OP's question so I will not go into much detail about them here. You can PM me if you want to learn more about them.
I can't seem to figure out why my search button jumps to the second line. As far as I can tell, I only have it set to be one line (45px) thick and it is ignoring that. Help please?

Forgot to add the script i'm using to actively change the button appearance.
$(document).ready(function(){
// select element styling
$('select.select').each(function(){
var title = $(this).attr('title');
if( $('option:selected', this).val() != '' ) title = $('option:selected',this).text();
$(this)
.css({'z-index':10,'opacity':0,'-khtml-appearance':'none'})
.after('<span class="select">' + title + '</span>')
.change(function(){
val = $('option:selected',this).val();
$(this).next().text(val);
})
});
});
You have whitespace in your code and your input element is set to display as inline-block and not floated properly. That's what's causing that extra space that doesn't show up in Dev Tools.
If you change float: center to float: left on that .summonerSearch element, it will be fine.

I'm new to Angular but I'm trying to implement a textbox that allows users to enter in links. I only want to support links, and otherwise I want to block all html from being presented as such. I could theoretically use something other than a textarea, but my requirements are that it must be bound to a variable in my scope (right now with ng-model) and I cannot accept html tags other than '< a >'
Here is my example plnkr
In the example, I would like the second seeded item to display as a link, blue and underlined. However, the third item should display as it is currently shown (without interpreting it as html).
HTML:
<textarea maxlength="160" ng-model="val.text"></textarea>
<div class="btn" ng-click="submit()">Submit</div>
<br><br>
<div ng-repeat="item in items">
{{display(item)}}
</div>
JS:
$scope.submit = function() {
if (!$scope.val.text) return
$scope.items.push($scope.val.text);
}
$scope.display = function(txt) {
return txt;
// something here? if txt contains <a> and </a> indicate
// that we should display as html
}
I use following style attribute so when i will start typing in text box suppose 'railway'then it should get enter in text box like 'RAILWAY' without pressing CapsLock
<input type = "text" class = "normal" name = "Name" size = "20" maxlength = "20"> <img src="../images/tickmark.gif" border="0" style='text-transform:uppercase'/>
but I am not getting desired output by using this attribute
The best method would be to change the styling on your form to display uppercase:
input.normal
{
text-transform:uppercase;
}
SEE EXAMPLE
However this will not actually convert the string to uppercase, just style it to appear this way.
Therefore then when the data is submitted, use whatever server side language to convert the string to uppercase for purposes of storing in the database etc. For example with .NET you would do:
str.ToUpper();
You can accomplish this using CSS, if you only care about stylistic aspect:
.normal { text-transform: uppercase; }
If you need the text itself to be in all-caps (which is probably what you meant, sorry), combine with a bit of jQuery (it can be done without jQuery, too, but what's the point in that?):
$('.normal').change(function() {
$(this).val($(this).val().toUpperCase());
});
Example: http://jsfiddle.net/HackedByChinese/QwSSe/1/
You need to put your text transform in your Input tag, not your Image tag. Like this.
<input type = "text" class = "normal" name = "Name" style="text-transform:uppercase;" size = "20" maxlength = "20">
<img src="../images/tickmark.gif" border="0"/>
In my site, I would like to implement a textbox where people can input a set of strings separated by a separator character.
For example the tags textbox at the bottom of this page: tags(strings) delimited by space(separator).
To make it more clear to the user, it would make a lot of sence to give each string a different background color or other visual hint.
I don't think this is possible with a regular input[text] control.
Do you deem it possible to create something like that with javascript? Has somebody done this before me already? Do you have any other suggestions?
Basic Steps
Put a textbox in a div and style it too hide it.
Make the div look like a text box.
In the onClick handler of the div, set the input focus to the hidden text box.
Handle the onKeyUp event of the hidden text box to capture text, format as necessary and alter the innerHtml of the div.
Tis quite straightforward. I'll leave you to write your formatter but basically you'd just splitString on separator as per the Semi-Working-Example.
Simple Outline
<html>
<head>
<script language="javascript" type="text/javascript">
function focusHiddenInput()
{
var txt = document.getElementById("txtHidden");
txt.focus();
}
function formatInputAndDumpToDiv()
{
alert('Up to you how to format');
}
</script>
</head>
<body>
<div onclick="focusHiddenInput();">
Some label here followed by a divved textbox:
<input id="txtHidden" style="width:0px;" onKeyPress="formatInputAndDumpToDiv()" type="text">
</div>
</body>
</html>
Semi-Working Example
You still need to extend the click handlers to account for tag deletion/editing/backspacing/etc via keyboard.... or you could just use a click event to pop up another context menu div. But with tags and spacer ids identified in the code below that should be pretty easy:
<html>
<head>
<script language="javascript" type="text/javascript">
var myTags=null;
function init()
{
document.getElementById("txtHidden").onkeyup= runFormatter;
}
function focusHiddenInput()
{
document.getElementById("txtHidden").focus();
}
function runFormatter()
{
var txt = document.getElementById("txtHidden");
var txtdiv = document.getElementById("txtBoxDiv");
txtdiv.innerHTML = "";
formatText(txt.value, txtdiv);
}
function formatText(tagText, divTextBox)
{
var tagString="";
var newTag;
var newSpace;
myTags = tagText.split(' ');
for(i=0;i<myTags.length;i++) {
newTag = document.createElement("span");
newTag.setAttribute("id", "tagId_" + i);
newTag.setAttribute("title", myTags[i]);
newTag.setAttribute("innerText", myTags[i]);
if ((i % 2)==0) {
newTag.style.backgroundColor='#eee999';
}
else
{
newTag.style.backgroundColor='#ccceee';
}
divTextBox.appendChild(newTag);
newTag.onclick = function(){tagClickedHandler(this);}
newSpace = document.createElement("span");
newSpace.setAttribute("id", "spId_" + i);
newSpace.setAttribute("innerText", " ");
divTextBox.appendChild(newSpace);
newSpace.onclick = function(){spaceClickedHandler(this);}
}
}
function tagClickedHandler(tag)
{
alert('You clicked a tag:' + tag.title);
}
function spaceClickedHandler(spacer)
{
alert('You clicked a spacer');
}
window.onload=init;
</script>
</head>
<body>
<div id="txtBoxDivContainer">
Enter tags below (Click and Type):<div id="txtBoxDiv" style="border: solid 1px #cccccc; height:20px;width:400px;" onclick="focusHiddenInput();"></div>
<input id="txtHidden" style="width:0px;" type="text">
</div>
</body>
</html>
Cursor
You could CSS the cursor using blink (check support) or otherwise just advance and hide as necessary an animated gif.
This is quite interesting. The short answer to your question is no. Not with the basic input element.
The real answer is: Maybe with some trickery with javascript.
Apparently Facebook does something close to this. When you write a new message to multiple persons in Facebook, you can type their names this sort of way. Each recognized new name is added a bit like an tag here and has an small cross next to it for removing it.
What they seem to do, is fake the input area size by drawing an input-looking box and removing all styling from the actual input with css. Then they have plenty of logic done with javascript so that if you have added an friend as a tag and start backspacing, it will remove the whole friends name at once. etc.
So, yes, it's doable, but takes plenty of effort and adds accessibility problems.
You can look how they do that at scripts like TinyMCE, which add such features to textareas. In textareas you can use HTML to colorize text.
You can use multiple textboxes
textbox1 <space> textbox2 <space> textbox3 ....
and so on... You can then apply the background-color style to each textbox.
